Shear zones

After seeing so many geolgical field trips and fiels camps in an orogenic belt, I grew an interest in shear zones. I used vorticity and anisotropy of magnetic susceptibility to characterize the structural deformation, and quantify the presence of pure vs. simple shear components.

But my next project on this topic is really different,  and really exciting! I am going to participate to IODP Expedition 405 - Tracking tsunamigenic slip across the Japan trench. I will use anisotropy of magnetic susceptibility from the frontal prism to characterize the magnetic fabric linked to the faulting process, and discriminate the superposition of multiple tectonic and/or sedimentary processes.
